  The value of \[\Delta H\] for the reaction\[{{X}_{2}}(g)+4{{Y}_{2}}(g)2X{{Y}_{4}}(g)\] is less than zero. Formation of \[X{{Y}_{4}}(g)\] will be favored at                                                                     [AIPMT (S) 2011]

A)  low pressure and low temperature

B)  high temperature and low pressure

C)  high pressure and low temperature

D)  high temperature and high pressure

Correct Answer: C

Solution :

               and The forward reaction is favoured at high pressure and low temperature. (According to Le-Chatelier's principle)
